I feel like he doesn’t care

Okay, so my period should be coming any time soon and my emotions are wacky.

Basically I was playing videogames with him and friends and I got really sad and got off, he didn’t even ask why when I said I’m going to bed. He didn’t ask how I was feeling, or anything. I feel so hurt. I wish I had someone to ask me how I’m feeling. I know I should handle my emotions on my own it just hurts laying in my bed alone right now crying when his last text was “sweet dreams”. How could I ask him for help and bring his mood down? But then he won’t even notice when I want his help or care. I feel so alone. I hate my period.
